Implementation and Performance Analysis of an Adaptive Vector Tracking Loop Utilizing Precise Satellite Orbit/Clock and Ionospheric Products

Shaohua Chen and Yang Gao

Abstract:	Vector delay lock loop (VDLL) aided by precise satellite orbit/clock, and atmospheric model is proposed in this paper. The result shows that the position solution derived from the extended Kalman filter of VDLL is not influenced by the aiding information and a separate position filter is needed to improve the position accuracy utilizing the aiding information. A fault detection and exclusion method is integrated to VDLL to solve the inter-channel influence, which will improve the robustness of VDLL. A field test is conducted to demonstrate and verify the method’s performance.
